Noram Ventures Inc. (CVE:NRM) said on Wednesday sample assays from its Zeus claim block returned up to 1670 ppm lithium and an average of 621 ppm over 77 samples as it released an initial National Instrument 43-101 Technical Report on its 100% owned Clayton Valley Lithium Brine/Clay Project.
The Technical Report by Bradley Peek Msc included a detailed review of the exploration work completed to date, interpretations and conclusions, and recommendations for the next phases of work.
Noram’s land position in Nevada’s Clayton Valley consists of 888 placer claims covering 17,738 acres (7,178 hectares) in two non-contiguous claim blocks. The perimeter of Noram’s claims are located within 1 mile (1.6 kilometers) of Albemarle Corporation’s lithium brine operations.
Albemarle produces lithium at its plant from deep wells that pump lithium-rich brines from the basin beneath the Clayton Valley playa. The Albermarle plant is the only lithium producer in the United States and has been producing lithium at this location continuously since 1967.
While lithium brines may also exist beneath Noram’s claims, the Company has chosen to focus its initial efforts on the lithium-rich sediments (claystones).
In three phases of surface sampling Noram has established that lithium-rich sediments occur at surface over a large portion of its claims. This includes an area greater than one square mile (2.6 square kilometers) on the Zeus claim block where sample assay values ranged from a maximum of 1670 ppm Li to a minimum of 74.2 ppm Li and averaged 620.6 ppm lithium over the 77 samples tested.
In some areas the lithium-rich sediments are at least 100 feet (30 meters) thick and the base of these sediments has not been found in surface showings. Other sampling farther southwest on Noram’s South Block has discovered isolated areas of what appear to be the same sediments with similar anomalous lithium assays. This extension covers an area with a strike length of more than 6 miles (10 kilometers). However, it is yet to be determined if the sedimentary units are continuous over this entire length.
One of the keys to Noram’s Project is to determine if lithium can be economically extracted directly from the sediments.
To this end, Noram commissioned Membrane Development Specialists LLC to investigate the amenability of the sediments to lithium extraction using new, environmentally-friendly membrane processes. Their findings, although preliminary in nature, have shown that the bulk sample sediments tested were amenable to an acid leach, ultrafiltration and nanofiltration process to separate the lithium from the sediments and remove a large portion of the magnesium and calcium with no rejection of lithium.
Based on the interpretations and conclusions from exploration work and testing to date, it is recommended that Noram:
